How can we measure the depth of sea by using SONAR?
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
What is the sound of sea waves called?
The sound of sea waves is commonly referred to as the "lull" or "roar" of the waves. The soothing and rhythmic sound of waves crashing against the shore is often described as calming and peaceful.
What is device is used that emits a sound wave to measure the ocean floor?
A sonar device is commonly used to emit sound waves and measure the ocean floor. Sonar works by sending sound waves downward, which bounce off the sea floor and return, providing information about the depth and characteristics of the ocean floor.
How is the depth of sea measured using ultrasonic waves?
It's done using exactly the same principle as radar:-- You know the speed of sound through the seawater.-- You send out a pulse of sound underwater ... a tremendously loud "BEEP". Also, at exactly the same instant, you start a clock.-- The sound travels down to the bottom and hits the sea floor. Some of the sound is absorbed, and some bounces off of the sea floor. The part that bounces off sprays away in all different directions. A small part of the sound energy goes back exactly the way it came ... back toward your equipment on the boat.-- Back on the boat, your clock is still running, and your sensitive equipment is listening for a weak echo of a beepto come up from the sea floor. When it hears the echo, the clock stops.-- Multiply the (speed of sound in the water) by the (length of time it took for the beep echo to return). The answer is the (distance the sound traveled on its round-trip) ... which is exactly double the depth of the water under the boat.Ultrasonic (inaudible) sound is used for two main reasons:1). Shorter wavelengths can resolve smaller details, giving a clearer picture of the topography on the sea floor. Same reason 'ultrasound' is used for medical imaging.2). Probing with loud audible sound signals would drive the people on the boat crazy. So they use sound that people can't hear. That way, only all the whales and other sea life within a thousand miles are upset and irritated and have their feeding and mating processes and social communication disrupted.
How do you determine the length of a wave base?
The length of a wave base is typically determined by multiplying the water depth by a factor that depends on the type of wave and the shape of the sea floor. In general, for deep water waves, the wave base is about half the wavelength, and for shallow water waves, it's about equal to the water depth. Measurements and calculations based on wave characteristics are usually used to estimate wave base length.

How does an echo sounder work?
An echo sounder works by sending out sound waves into the water and measuring the time it takes for the sound waves to bounce off an object or the sea floor and return to the device. By calculating the time taken for the sound waves to return, the device can determine the depth of the water or the distance to the objects in the water.
How do you measure the depth of sea using sonar?
an ultra sound wave is sent by a transmitter when it touches the ocean/sea bed it gets reflected and travels to the detector by using the formula distance=speed X time w e can derive the formula 2d=v X t since the distance is double (the waves travel down and up) v is the speed of sound in water and t is the time taken
What is the instrument used to measure the depth of sea called?
The instrument used to measure the depth of the sea is called a bathymeter or echo sounder. It sends sound waves to the ocean floor and measures the time it takes for the sound waves to bounce back, allowing for the calculation of water depth.
What is device is used that emits a sound wave to measure the ocean floor?
A sonar device is commonly used to emit sound waves and measure the ocean floor. Sonar works by sending sound waves downward, which bounce off the sea floor and return, providing information about the depth and characteristics of the ocean floor.
How can sound waves be used to locate a shoal of fish?
Echo sounding measures the time it takes a sound wave to hit the sea floor and return, knowing the speed of sound in water allows a depth to be calculated, if you have an existing depth map and a GPS , any differences between the map and your reading, could indicate a shoal of fish has sent back a false depth reading.

How fast do sound waves travel near sea level?

What is the instrument used to send down sound waves in the sea?
an amplifier
What are some examples of marine habitats?
The Pressure increases with depth The oxygen concentration levels decreases with depth There is the action of waves. There is alternative rise and fall of sea water twice as day, or simply tide action.
